I admit this mail is really hard to read and reply to, so it's possible

Yup. Why do you want to use the 'create' command?

/dev/sg3 is your autochanger, not /dev/sg2.

Fix this here.

The above two lines are probably a performance killer.

Interesting output :-)
The mtx's I know report problems in a different format. Which mtx is it
you're calling here?
Anyway, as the configuration is incorrect, and mtx, and thus
mtx-changer, don't work correctly, it's not possible to tell anything
valuable from the following output... with exceptions :-)

Interesting. When mtx does not work, and mtx-changer does not work, too,
there should be some messages and probably an error here.

And now you wonder where the volume Montag comes from?
Probably you deleted the pool it belonged to, labeled it using btape, or
got that volume from another Bacula installation.

mtx-changer does not work.
You've got to get mtx-changer working first. mtx-changer relies on mtx,
so unless you get mtx to report the device status correctly, it's no use
trying to operate Bacula.
First, make sure you've got a working SCSI installation (use tar or dd
to test the tape). Then, investigate why mtx can't operate the
Superloader. Actually, I'm quite sure this *can* work... watch the
system log during mtx operation.
Once you've got this right, use btape for the tape testing, following
the manual.
